Blocked Callers and Test Numbers: Managing Your Whitelist

The caller management tools let you control which numbers can reach your AI agent and which are blocked. Blocking is useful for persistent spam callers that slip through automatic detection, former employees who keep calling your business line, or any number you do not want consuming your voice minutes. Blocked callers hear a brief message ('This number is not able to reach this business') and the call ends. No AI minutes are used, and the call does not appear in your main call log.

Test numbers are equally important. When you are setting up your AI agent or testing changes to your FAQ, you do not want those test calls counted against your monthly minutes. Add your personal phone number and your team's numbers to the whitelist in Settings > Call Handling > Test Numbers. Calls from whitelisted numbers are handled normally by the AI but are flagged as test calls and do not consume paid minutes. This lets you test as often as you need without worrying about usage.

Both blocked and whitelisted numbers can be managed individually or in bulk. You can add numbers one at a time from the settings page, or import a CSV list for bulk operations. Blocked numbers can be temporary (block for 30 days) or permanent. The block list is shared across your organization, so if one team member blocks a number, it applies to all phone lines associated with your account.
